• Items: Gets a list of RadioButtonData objects, which represent the individual radio buttons in the group.
• SelectedItem: Gets or sets the currently selected radio button in the group.

Methods

• AddButton: Adds a new radio button to the group.
• AddSeparator: Adds a separator to the group.
• Clear: Removes all radio buttons and separators from the group.
• Dispose: Disposes of the radio button group, releasing any associated resources.

Events

• SelectedChanged: Raised when the selected radio button in the group changes.

Examples

// Create a new radio button group.
RadioButtonGroup radioButtonGroup = new RadioButtonGroup();

// Add some radio buttons to the group.
radioButtonGroup.AddButton(new RadioButtonData("Option 1", true));
radioButtonGroup.AddButton(new RadioButtonData("Option 2", false));
radioButtonGroup.AddSeparator();
radioButtonGroup.AddButton(new RadioButtonData("Option 3", false));

// Add the radio button group to a layout control.
StackPanel stackPanel = new StackPanel();
stackPanel.Children.Add(radioButtonGroup);

// Handle the SelectedChanged event.
radioButtonGroup.SelectedChanged += delegate (object sender, EventArgs e)
{
    Console.WriteLine("Selected radio button changed.");
};

Remarks

• Radio button groups are typically used in dialog boxes and other user interface elements to allow the user to select a single option from a set of mutually exclusive choices.
• The RadioButtonData class is used to specify the text and initial selection state of individual radio buttons in the group.
• The SelectedItem property returns null if no radio button in the group is selected.
